Build pytorch, ONNX, caffe2 with Anaconda python3.6

[astroli]

Here is my procedures of building pytorch + caffe2 + ONNX in Ubuntu 17.04
for http://pytorch.org/tutorials/advanced/super_resolution_with_caffe2.html

Install python

./Anaconda3-4.4.0-Linux-x86_64.sh
export PATH=~/anaconda3/bin:$PATH

conda install -c statiskit python-dev
conda install -c conda-forge pybind11
conda install future

Build, install pytorch (torch.onnx missed)

#conda install pytorch torchvision -c soumith
git clone --recursive https://github.com/pytorch/pytorch.git
cd pytorch
python setup.py install

Build, install ONNX

git clone https://github.com/onnx/onnx.git
cd onnx
python setup.py install

Build, install ONNX-CAFFE2

git clone https://github.com/onnx/onnx-caffe2.git
cd onnx-caffe2
python setup.py install

Build caffe2 with python3

git clone https://github.com/caffe2/caffe2.git
cd caffe2
mkdir build
cd build
cmake .. -DPYTHON_EXECUTABLE=/anaconda3/bin/python -DPYTHON_LIBRARY=/anaconda3/lib/libpython3.6m.so -DPYTHON_INCLUDE_DIR=~/anaconda3/include/python3.6m
make -j4
export PYTHONPATH=pwd

@astroli Is there a complete guide for installing, pytorch, onnx and caffe2 installation? I have anaconda2 and ubuntu 16.04

[astroli]

Anaconda2-5.0.1-Linux-x86_64.sh

export PATH=~/anaconda2/bin:$PATH

git clone --recursive https://github.com/pytorch/pytorch.git
cd pytorch/
python setup.py install
cd ..

onnx-caffe2 will install caffe2, onnx and onnx-caffe2

See install.sh

git clone --recursive https://github.com/onnx/onnx-caffe2.git
cd onnx-caffe2
./install.sh
